Description
Technical field
The present invention relates to catalyst preparation equipment fields, are used for acetylene hydrochlorination catalyst without mercury system in particular to one kind
Standby infuser.
Background technique
Vinyl chloride monomer is the basic material for synthesizing chemical products, is widely used in all fields of national economy.Currently, work
The method for producing vinyl chloride in industry mainly has two kinds of routes of ethylene process and acetylene method, and ethylene process is using ethylene as raw material, with chlorine
Gas reacts under the effect of the catalyst generates dichloroethanes, then vinyl chloride is made by thermally decomposing.Acetylene method is direct by acetylene
Vinyl chloride is generated under the effect of the catalyst with hydrogen chloride.
It is domestic still mainly carbide acetylene method to be selected to produce vinyl chloride due to the energy pattern of China " the more gas of coal are few " now,
Account for about the 80% of vinyl chloride total output by the vinyl chloride that acetylene method synthesizes.Currently, acetylene hydrochlorination method synthesis vinyl chloride thereof is industrial
Still use the mercuric chleride catalyst using active carbon as carrier.Mercury chloride severe toxicity, and easily distil during the reaction and cause to be catalyzed
The mercury chloride of agent inactivation, loss causes damages to biology and natural environment.As China in recent years is to Heavy Metal Pollution Control power
The increasing of degree and increasingly scarcity, the research of novel low mercury or even catalyst without mercury of mercury resource are extremely urgent.
Infuser has a wide range of applications in chemical field, for mixing, drying, impregnate material, leads in catalyst preparation
There is indispensable role in domain.
In catalysis agent producing process, by active component by being very important a step, work on dip loading to carrier
It is mainly completed using infuser in industry, and in the production of catalyst without mercury, often to impregnate some corrosive materials.
And most of infuser does not all account for this problem on the market.
This impregnator is mainly for the preparation of acetylene hydrochlorination catalyst without mercury, currently, most of infusers are most on the market
The production of catalyst without mercury is not examined.In catalyst without mercury production process, the strong material of some corrosivity is often impregnated, it is existing
Infuser inner wall be all mostly it is made of metal, inner wall and vacuumizing filtration device and vacuum tube can become rusty over time
Erosion, both will cause the loss of material, and can also shorten the service life of infuser.Meanwhile most of device precisely processed is static state on the market
Dipping causes material dipping to be not enough, and impregnating effect is not good enough.And most of infusers are added using heating plate on the market
Heat is easy initiation accident so that material uneven heating is even.
Summary of the invention
To solve the above problems, the present invention discloses a kind of infuser for being used to prepare acetylene hydrochlorination catalyst without mercury, it is interior
Shell anticorrosion substantially increases service life.And material dipping is sufficiently, and impregnating effect is good.
In order to achieve the above objectives, technical scheme is as follows:
A kind of infuser being used to prepare acetylene hydrochlorination catalyst without mercury, it is characterised in that: turned round including rack and bicone
Vacuum sealing cylinder, between double conical cylinder setting and left frame and right rack, the inner-wall spraying glass-lined coating of the double conical cylinder,
It is enclosed with collet on the outside of the seal with double-cone cylinder, the collet is made of carbon steel, and heating layer is formed between collet and cylinder.Institute
It states and is connected to right axle on the right side of double conical cylinder, vacuum tube is provided in right axle, vacuum tube is located at the intracorporal one end chain of cylinder and is connected to pumping very
Air filter, other end are connected with vacuum meter.The right axle is connected with transmission device, transmission device be located at right bottom of the frame
Motor be connected.
When work, in tank under vacuum conditions, it is passed through steam into collet or hot water is heated, heat passes through in tank body
Wall is contacted with wet stock, and the steam evaporated after wet stock heat absorption is pumped by vacuum pump through Vacuum exhaust tube.Due in tank body
Revolution in vacuum state, and tank body makes the continuous revolution inside and outside up and down of material, constantly stirs dried material and updates drying
Surface, accelerates the evaporation of the liquid contained by dry material, therefore accelerates the impregnating speed of material, improves pickling efficiency, reaches uniform
The purpose of dipping.
Further, the cylinder is heated using collet, and tank body under vacuum conditions, hot steam is passed through into collet, with
Cylinder lumen carries out heat exchange by dry wet stock, enables material thermally equivalent, sufficiently, dipping effect is good for dipping.
Further, the vacuumizing filtration device is made of titanium, keeps its anticorrosion ability more preferable, extends its practical longevity
Life, while the hardness of titanium is big, it is therefore prevented that the residue for being mixed into material is generated due to stirring when production, substantially increases product
Clarity.Further, the right axle and cylinder are sealed using sealing ring, keep its sealing effect more preferable.
Further, the double conical cylinder top is provided with feed inlet, and lower part is provided with discharge port, and feed gap dimension is greater than
Discharge port size, feed inlet also can be used as manhole use.
Further, feed inlet is provided with sealing upper cover, and discharge port is provided with sealing lower cover, sealing upper cover and sealing lower cover
On be provided with handle.
In conclusion the present invention has the advantage that the present invention is used to prepare acetylene hydrochlorination mercury-free compared with prior art
The infuser of catalyst keeps dry materials uniform using rotary drying, better than traditional infuser dipping effect.Bipyramid shell
Inner wall is coated with glass-lined coating, substantially increases the ability of corrosion protection of equipment, while vacuumizing filtration device is made using titanium, mentions
Reduce pollution of the external factor for material while high life.Cylinder inboard wall is smooth, and material is enable easily to be discharged, and reduces
Because worker shovels out damage of the material to equipment, the service life of equipment is extended.
